The bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. Input data are shifted into a 32-bit shift registers that can then be retained in a 32-bit latch. To reduce any possible clock feed through noise, the latch enable bar should be left high until all bits are clocked in. Data are clocked in during the r...
